Ultima 1 engine: first public release

[Dino]

In the files section you can find a first release of the Ultima 1
project, which is still in map viewer stage. The latest changes are
fixes with movement (you can move freely in all directions and keep
arrow keys held for fast movement) as well as the ability to save a
computer-generated world map by pressing the 'S' key.

You will also find a sample computer-generated map in the files
section.

Use the arrow keys to move around the map. The top-left corner tile
serves as the tile viewer; you can toggle it by pressing 'T'.
Otherwise use Page Up and Page Down to scroll through the game's
tiles.

You can press ESC to quit, or close the window.

There are some known bugs, there exists a TODO list, etc, but I won't
post them now since I'd like to sleep before 4am. One thing you'll
surely notice is that some tiles are wrong (signs, towns, castles and
dungeons). Relax. I'll fix it in time.

Any comments, complaints, bug reports, etc are definitely welcome.
